Pariente issued her latest comments on the issue in a concurring opinion in a case in which she and the other justices unanimously rejected Death Row inmate Charles Peterson’s claim that his lawyer’s failure to use an eyewitness identification expert constituted ineffective assistance of counsel.

In the eight-page opinion joined by Justice Peggy Quince, Pariente also said that previous Supreme Court rulings may have left the impression that eyewitness expert testimony is inadmissible. Instead, Pariente wrote, such expert testimony should generally be allowed to help juries decide on the reliability of eyewitnesses, especially in cases that rest substantially or entirely on eyewitnesses.

“Specifically, I would adopt the rationale of the Supreme Court of Connecticut … and conclude that this Court’s precedent, which suggests that factors affecting eyewitness testimony are within the common experience of jurors, is ‘out of step with the widespread judicial recognition that eyewitness identifications are potentially unreliable in a variety of ways unknown to the average juror,'” Pariente wrote.

Pariente noted that the Innocence Commission appointed by the high court to analyze wrongful convictions highlighted eyewitness misidentification, which has been a factor in 75 percent of convictions later exonerated through DNA evidence nationally.

The current eyewitness expert standard is based on a 31-year-old death penalty cases involving Paul Beasley Johnson in which the Supreme Court decided that “a jury is fully capable of assessing a witness’ ability to perceive and remember…without the aid of expert testimony.”

But since then, social scientists have identified a variety of factors that contribute to misidentification. Courts in New Jersey, Utah, Oregon and Connecticut also allow expert testimony in eyewitness cases, Pariente wrote.

“As the burgeoning body of scientific research indicates and courts across the country increasingly recognize, expert witness testimony on the reliability of eyewitness identifications can be a ‘powerful tool in helping the criminal justice system achieve its goal of convicting the guilty while acquitting the innocent,'” she wrote.

Eyewitness identification is compelling testimony that often leads to convictions, said Seth Miller, executive director of the Innocence Project of Florida. But it is “naïve” to assume that jurors know enough to assess the reliability of an eyewitness, he said.

“Jurors can be prejudiced and overly compelled by that seminal moment in a trial where the defendant points at a person and says, ‘That is the person who raped me.’ And that can overshadow all of the other infirmities that exist with how the eyewitness identification may have happened,” Miller said. “That’s the kind of stuff these experts talk about and testify to. And these are things that jurors don’t know about … but they’ve been studied and proven in an uncontradicted way by people within the social science community over the past 30 years.”
